Myriophyllum mattogrossense

Milfoil

Definitely the easiest of all Myriophyllum present in the aquaristic – this species grows well even without introducing CO2, which however becomes necessary in case of intense light.

The color varies from dark green to a pale red, based on the intensity of the light, but the phenomenon only affects the most exposed leaves.

Aquarium equipment

The feather-like stems of Myriophyllum mattogrossense are very decorative, 30-60 cm long, with finely divided bright green leaves up to 5 cm wide. In good light conditions the leaves spread out like a fan.

Myriophyllum mattogrossense is a relatively easy to grow plant, grows fast and is suitable for background. It must be pruned frequently to maintain its bushy shape.

Plant care

This aquatic plant adapts to different light conditions, changing its appearance and its growth rate.

Water care

Myriophyllum mattogrossense feels best in soft and rather acidic waters. If the pH drops below 6.5 it absorbs large amounts of nutrients.

The temperature must never drop below 20°C, we recommend between 24 and 28. For limited periods it also resists 30-32°C.
